ditional functions
D37 EXPORT
You need the D37 function if you want to create your own cycles and
integrate them in the TNC. The Q parameters 0 to 99 are effective only
locally. This means that the Q parameters are effective only in the
program in which they were defined. With the D37 function you can
export locally effective Q parameters into another (calling) program.
Example: The local Q parameter Q25 is exported
Example: The local Q parameters Q25 to Q30 are exported
N56 D37 Q25
N56 D37 Q25 - Q30
The TNC exports the value that the parameter has at the
time of the EXPORT command.
The parameter is exported only to the presently calling
program.
